Overview
Orthostatic BP changes associate with nocturnal dipping patterns in elderly hypertensives; leaves open whether this informs screening or outcomes.
Structured PICO
Is abnormal diurnal blood pressure variation related to abnormal postural blood pressure variation in elderly hypertensive patients?
P
Population
110 asymptomatic hypertensive elderly subjects, consisting of 29 subjects with white-coat hypertension and 81 with sustained hypertension (14 extreme dippers, 56 dippers, 11 nondippers).
I
Intervention
70 degrees head-up tilt test to assess postural blood pressure variation
C
Comparator
Comparison among extreme dippers, dippers, nondippers, and white-coat hypertensive subjects
O
Outcome
Postural blood pressure variation (change in systolic blood pressure) during 70 degrees head-up tiltsurrogate
In elderly hypertensive patients, extreme nocturnal blood pressure dipping is strongly associated with orthostatic hypertension, whereas nondipping is associated with orthostatic hypotension.
